-6r + 1 = -17, then (17+1)=18=6r, so r=(18/6)=3. The answer is r=3
The 'solution' is the number that 'r' must be in order to make the statement true.Here's how to find it:6r - 1 + 6r = 11Add 1 to each side:6r + 6r = 12Clean up the left side:12r = 12Divide each side by 12:r = 1
r2+6r-7 = (r+7)(r-1) when factored
-2 - 2r or -2(1 - r)
You are searching for the value of r.-7r + 6 = 9 - 6r + 1Notice the 9 and the 1 on the right side. Since they are common factors (terms not attached to x), they can be added.-7r + 6 = -6r + 10Subtract 6 from both sides to eliminate the 6 on the left.-7r = -6r + 4Add 7r to both sides, leaving r-terms on only one side.0 = r + 4Subtract 4 from both sides, so one side is constant and the other is the variable.-4 = rThe answer is -4 is equal to r.
yes it does!
-16
9r = 3r + 6 subtract 3r from both sides 6r = 6 divide both sides by 6 r=1 ■
1 + 2 + 6 + 8 = 17
